Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm *LY8D<:zs  
Type: Double Bounces f|(M.U-  
The '****' denotes a possible internal focus x,'!gT:j  
RMS is the RMS spot radius on axis at the primary wavelength. fc>L K7M  
RMS values of 0.00 indicate that an accurate RMS GC'O[q+  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is Ax}JLPz5'  
non-rotationally symmetric or uses non-standard surfaces.
